摘要: 該文分析了在立體視覺系統(tǒng)下未定標(biāo)圖像間的對(duì)極幾何關(guān)系,通過證明虛擬平面的平面射影坐標(biāo)與立體射影坐標(biāo)的關(guān)系,提出了一種在射影幾何意義下進(jìn)行立體視覺重建的幾何方法,在計(jì)算轉(zhuǎn)移矩陣及重建點(diǎn)的立體視覺時(shí),采用精確的非線性算法,提高了算法的精度。

Abstract: Epipolar geometry and projective geometry between uncalibrated images in stereo vision system is analyzed and a geometrical method for projective reconstruction of stereo vision is presented after proving the relationship between the plane projective coordinates and stereo projective coordinates. The accurate nonlinear algorithm is adopted to compute the homography and projective coordinates . Experimental results demonstrate a high degree of accuracy of 3D reconstruction. -
